    Modal Expansionism.Alexander Roberts - 2019 - Journal of Philosophical Logic 48 (6):1145-1170.
    There are various well-known paradoxes of modal recombination. This paper offers a solution to a variety of such paradoxes in the form of a new conception of metaphysical modality. On the proposed conception, metaphysical modality exhibits a type of indefinite extensibility. Indeed, for any objective modality there will always be some further, broader objective modality; in other terms, modal space will always be open to expansion.

    Relative Necessity and Propositional Quantification.Alexander Roberts - 2020 - Journal of Philosophical Logic 49 (4):703-726.
    Following Smiley’s influential proposal, it has become standard practice to characterise notions of relative necessity in terms of simple strict conditionals. However, Humberstone and others have highlighted various flaws with Smiley’s now standard account of relative necessity. In their recent article, Hale and Leech propose a novel account of relative necessity designed to overcome the problems facing the standard account. Nevertheless, the current article argues that Hale & Leech’s account suffers from its own defects, some of which Hale & Leech (...)

    Imprecise Quantification.Alexander Roberts - 2019 - Proceedings of the Aristotelian Society 119 (3):357-367.
    Following David Lewis, Ted Sider has famously argued that unrestricted first-order quantification cannot be vague. His argument was intended as a type of reductio: its strategy was to show that the mere hypothesis of unrestricted quantifier vagueness collapses into the claim that unrestricted quantification is precise. However, this short article considers two natural reconstructions of the argument, and shows that each can be resisted. The theme will be that each reconstruction of the argument involves assumptions which advocates of vague quantification (...)

    From Physical to Metaphysical Necessity.Alexander Roberts - forthcoming - Mind.
    Let Nomological Bound be the thesis that there is nothing objectively possible beyond what is physically possible. Nomological Bound has struck many as a live hypothesis. Nevertheless, in this article I provide a novel argument against it. Yet even though I claim that Nomological Bound is false, I argue that the boundaries of objective possibility can still be characterized intimately in terms of physical necessity. This is philosophically significant, for on a natural understanding it constitutes the powerful anti-sceptical result that (...)

    Two Morals About a Modal Paradox.Alexander Roberts - 2020 - Synthese 198 (10):9873-9896.
    Chisholm’s paradox serves as an important constraint on our modal theorising. For example, one lesson of the paradox is that widely accepted essentialist theses appear incompatible with metaphysical necessity obeying a logic that includes S4. However, this article cautions against treating Chisholm’s paradox in isolation, as a single line of reasoning. To this end, the article outlines two crucial morals about Chisholm’s paradox which situate the paradox within a broad family of paradoxes. Each moral places significant constraints on the paradox’s (...)
